No, just 243 and 270

Don't be a blouse, sand that channel out so its making no contact. Try it again then.

Mmm do you think that's rubbing in there? Is it smoother than the rest of the channel? Sure looks like it and may be the/a reason for the flyer.

Hot glue is not a suitable bedding compound imo, far to flexible.

Can you get a close up of the first 2/3 inches of the stock at the muzzle end, few angles

If it was me, and I'm a rough cnut and know nothing about Winchesters, I'd sand that channel smooth, it almost looks like a patch of rubbing to one side in that first pic

Bit of fingernail stuck between barrel and stock is my guess :D
